Abiotic and biotic stresses applied to one part of a plant induce an information flow that informs distal parts in the plant about these threats. Numerous traveling components have been identified to participate in axial and radial transfer of treat information to distal organs. Three fast traveling signals (electric, Ca2+ and ROS waves) have been proposed to participate in systemic signal propagation. However, whether and how these signals are connected to each other, how they are initiated at the threated organ and decoded into a threat-specific response in the distal organ is still enigmatic. I will describe our present knowledge with focus on these fast traveling signals, and provide ideas for experimental approaches to address open questions.
